Abstract :
A 20-bit sequential character recognizer utilizing the domain wall wire technology discussed in a companion paper is described. The recognizer is e specially well-suited for use in portable battery operated systems because no standby power is dissipated and the operating voltage is only 2 volts. During code transmission the energy required per bit is approximately 1 μJ. The device is coded by punching an appropriate set of holes in a plastic strip. Still, it can be fully tested before coding. This allows mass production of the device with individual field coding made highly practical.
